Study on interaction between soil and structure

All civil structures are built on the ground. Therefore, when designing and constructing a civil structure, it is important how to evaluate the soil-structure interaction. The soil-structure interaction depends on the various factors, such as both rigid difference, nonlinearity, and the characteristics of external force. Accordingly, in order to comprehend these factors correctly, it is necessary to solve the mechanical behavior of soil and structures by sophisticated experiments and numerical analysis.
In recent years, furthermore, the design of civil structures has been made the shift to the performance based design from the specification based design, so we need to investigate not only the deformation and the damage but also the demand performance and the marginal state of structures. Based on the above-mentioned subject, we are carrying out research for various civil structures, such as a group pile foundation, a culvert tunnel, and a reinforced earth through the many experiments and numerical analysis to elucidate the soil-structures interaction and construct the rational design approach.

Technical approach for poverty reduction in developing countries from geotechnical engineering view point

A lot of developing countries suffer from poverty caused by poor infrastructure such as a farm road or a pond in the rural area, nevertheless these countries make a living by agriculture. In the rainy season, unpaved roads are impassable due to muddy conditions.
To solve this problem, our team developed road maintenance method with using “Sac” based on the policy that local people should solve the problem of developing country with simple method suitable for local site. Now our activities are expanding into various countries.
